How to make cross-section data along topographic surface

Hello,

I have matrix dimension 431x690 on a 3D surface (X,Y,Z). and would like to get cross section start from a point (200:214,310:370). This data provide matrix 15x61.

Any people can help me. I am eager using matlab.

Thank you!

Let X,Y,Z be your 431X690 matrices. To extract 200:214,310:370, use:

X1 = X(200:214,310:370) ;
Y1 = Y(200:214,310:370) ;
Z1 = Z(200:214,310:370) ;

Your X1,Y1,Z1 will be of size 15X61.

I wanna make profile along 3D surface. How to do that?

This picture is my real problem. I can't figure it out how to extract data from the red line.
